Nightwing is .............. Lar-Zod (Yes Zod's son), Aka Chris Kent. Who is apparently randomly aging now that he's out of the phantom zone (didn't we see this in flash with his kids?) His mother Ursa shows up at the end of the issue. Flame bird is......Thara Ak-Var Supergirl's childhood friend. So she's out as a candidate for superwoman. I was really hoping for connor. Well at least it appears he's coming back in legion of 3 worlds.
